1 Claim.

My invention relates to new and useful improvements in an alloy, and has for its principal object the production of a coating that will adhere to a metallic surface to avoid deterioration thereof.

A further object of the invention is to provide a coating substance comprised of a variety of metallic elements and means to combine the elements in their molten state.

A still further object of the invention is to produce a substance molded in appropriate quantities as an article of merchandise.

The alloy consists of a mixture of lead, tin, silver, copper, and bismuth, and in the preparation of the composition it is preferred that the elements be used in about the following proportions-via, lead fi tin 20%, silver of 1%, copper 6 of 1%, and bismuth V of 1%.

Inasmuch as the elements require difierent degrees of heat to render the same to a molten state and to avoid deterioration of the elements that melt under a .lesser degree of heat, it is required that the elements be separately subjected to their respective required degree of hat to melt the same; namely, lead, tin, silver, copper, and bismuth, each is placed in a separate crucible to melt the elements to avoid disintegration of those requiring a lesser degree of heat to melt the same, and while in their molten state they are poured together, preferably, in their consecutive order as above tabulated beginning with lead, and thoroughly mixed at each pouring, after which and while in its molten state the alloy is poured into molds of anappropriate size for storage or transportation. The alloy thus compounded will melt simultaneously and without detrimental effect to the elements that melt with alesser degree of heat prior to mixing as above stated.

In the application of the alloy, pipes, sheet metal, or other structural iron, steel, copper, or the like, shall be first treated by chemically cleansing the surfaces, preferably by washing in caustic soda solution, pickled in muriatic acid, and then an appropriate flux is applied. After thus treated the metal is then dipped into the molten alloy which results in a deposit of alloy coating thereon suflicient to seal'the metal from the action of the elements or chemicals which otherwise would deteriorate by corrosion or otherwise. I

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is:

Analloy, consisting substantially 0t 79%% lead, 20% tin, 01' 1% silver, 1 of 1% copper, and ,4 01' 1% bismuth.
